Implement Calculators for Derived Metrics
nickman opened this issue · comments
Calculators should be implemented as a destination.
BaseDestination needs to be enhanced to support a MetricURI as a filter.
Calculators will either need Issue (#5) so that metrics are flushed all at once, or we need to implement a concurrency barrier to only fire a calc when all dependencies for the computation have been satisfied. (GPars DataFlow ?)
